Isotropic GUP bounds improved by a factor of 10^10

Established and constrained anisotropic GUP models

Enhanced the link between GUP and SME experimental limits

Abstract

In this proceedings, I outline recent efforts to constrain models based on generalized uncertainty principles (GUP) using limits on coefficients of the Standard-Model Extension. Two main results are reported: (1) bounds on isotropic GUP models are improved by a factor of $10^{10}$ compared to previous spectroscopic bounds; and (2) anisotropic GUP models are established and also constrained.
